Swift Tutorial - Tutorialspoint

An operator is a symbol that tells the compiler to perform specific mathematical or logical
manipulations. Objective-C is rich in built-in operators and provides the following types of
operators:

 Arithmetic Operators

 Comparison Operators

 Logical Operators

 Bitwise Operators

 Assignment Operators

 Range Operators

 Misc Operators

This tutorial will explain the arithmetic, relational, logical, bitwise, assignment and other
operators one by one.

Arithmetic Operators...........................................................................................................................

The following table shows all the arithmetic operators supported by Swift language.
Assume variable A holds 10 and variable B holds 20, then:

Operator Description Example

+ Adds two operands A + B will give 30

− Subtracts second operand from the first A − B will give - 10

* Multiplies both operands A * B will give 200

/ Divides numerator by denominator B / A will give 2

% Modulus Operator and remainder of after an

integer/float division

B % A will give 0

++ Increment operator increases integer value by one A++ will give 11
